Final answer:
The question asks about a character named Drysdale correcting someone about the pillars of a mansion, but the context provided is from a different scenario involving Mrs. Tilley and Sylvia, which does not allow for an accurate response.
Step-by-step explanation:
The question appears to be related to a piece of literature or a subplot within a television series or film. Without the specific context of the scene where "Drysdale corrects someone regarding the pillars of the mansion," it is difficult to provide a correct answer.
In traditional settings from classic television, Mr. Drysdale is a character from the show The Beverly Hillbillies, who often interacts with the Clampett family, including Jethro, Granny, Elly May, and Miss Hathaway. However, the reference provided by Mrs.
Tilley and Sylvia do not align with the show's context or characters, indicating that there might be confusion with another piece of literature or media. Therefore, the question cannot be accurately addressed based on the information provided.
